LEVER.

SPECIFICATION forming part of Letters Patent No. 445,558, dated February3, 1891.

Application filed October 20,1890. Serial No. 868,633. (No model.)

To all whom it may concern:

Be it known that I, GUSTAVE H. JANTZ, a citizen of the United States,residing at Oincinnati, in the county ofHamilton and State of Ohio, haveinvented certain new and useful Improvements in Levers; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, reference being had to the annexed drawings, which form partof this specification.

This invention relates to those mechanical appliances commonly known aslevers of the second class; and the first part of my improvementsconsists in providing such levers with a longitndinally-shiftablebearing that rests against the object to be moved, and said bearing hasa clam p-screw or equivalent fastener wherewith it is retained at anyspecific adjustment, as hereinafter more fully described.

The second part of my improvements consists in rendering this shiftablebearing vertically adjustable, so as to be readily adapted to the objectto be moved, as hereinafter more fully described.

The third part of my improvements consists in coupling the lover to aswivel-fulcrum, so as to facilitate handling the object to be moved, ashereinafter more fully described.

The fourth part of my improvements consists in rendering theswivel-fulcrum vertically adjustable, so as to adapt the lever to agreater variety of uses, as hereinafter more fully described.

In the annexed drawings,Figure 1 is a sectionized side elevation of alever provided with a longitudinally and vertically adjustableswivel-bearing and a vertically-adjustable swivel-fulcrum. Fig. 2 is anenlarged vertical section of a modified form of the swivel-fulcrum. Fig.3-is an enlarged side elevation of a modified form of thelongitudinally-shiftable bearing. Fig. 4. is a vertical section of amodified form of this bearing. Fig. 5 is a side elevation of anotherform of this bearing. Fig. 6 shows the manner of using another modifiedform of my invention.

A represents any suitable form of bar or other rigid appliance capableof being used as a lever for lifting heavy weights or other objects, and13 is ahandle that may be attached to the free end of this lever. Thefulcrum end of this lever may be bent upward, as represented at a inFig. 1, or downward, as seen at a in Fig. 3, to afford a verysecure holdon rounded objects; but for many purposes it is preferred to couple saidlever to a special fulcrum, the form generally preferred being seen inFig. 1. Here the lever is coupled at c-between a pair of ears 0, thelatter being provided with a screw-threaded shank D, that engages with afoot (I, by which arrangement the fulcrum end of said lever can beadjusted vertically and turned around either to the right or left; butin Fig. 2 the ears 0 project from a disk-shaped base E, and have acentral spindle F, Whose lower end is headed up at f for the purpose ofcoupling said ears to the foot d.

G is a washer that may be interposed between the foot d and base E todiminish friction. This construction, like that seen in the precedingillustration, affords a swivel-fulcrum for the lever, but has noprovision for vertical adjustment.

II in Fig. 1 is a slide capable of being shifted along the lever A andretained at any specific adjustment by a clamp-screw h or equivalentdevice, the upper side of said slide being furnished with ascrew-threaded shank 71, that engages with a hearing I. dis a serratedor roughened upper surface of this bearing. It is apparent that thisbearing I can be shifted longitudinally of lever A, so as to comedirectly under the object to be lifted, and then by adjusting thebearingI vertically and bringing it in contact with said object the latter willbe lifted the instant said lever is operated. A modified form of thebearing is seen in Fig. 3, the slide I-I being used alone, and having aspur J adapted to act against certain kinds of rounded objects. Thisillustration shows the clamp screw or bolt It on the side of said slideinstead of under it. A more elaborate form of bearing is seen in Fig. I,where it takes the shape of a saddle I, be ing concave at top and havingat bottom a headed shank z", wherewith said saddle is swiveled to theslide II, thus enabling said bearing to revolve upon said slide. Fig. 5shows the slide H with a rocking bearing 1 jointed thereto, whichbearing will readily adjust itself to anyinclincd surface on the objecttoibeliftedj In the modification seen in Fig. (3 the lover is forkedatits end to afford journal-bearings for a roller-fulcrum K, and theshiftable slide 11 is engaged under a heavy object, such as abook-caseor wardrobe L. 13y canting the case back. and permitting the lever tobear against its front the case can be held in this inclined position,if desired, or it can be rolled along on the small wheel K. It ispreferred to bend the handle of this form of lever, as seen at Z).

From the above description it is apparent that all the modificationsshowthe leading idea of the inventionthat is to say, they include abearing capable of being slid longitudinally of the lever-and thenfastened at whatever point will afford the best purchase against theobject to be moved; It is also apparent that the swivelfulcrum enablesthe lever to be readily swung around either to the rightor left for thepurpose of shifting the position of the object after it has been raisedoff'the floor or other-support. Finally, all the uses to which such anappliance is capable cannot be specified; but it is evident that thelever will be veryserviceable in stores, factories, and" for variousdomestic purposes.

I' claiin as my inve'ntion 1. Aleverof the second class provided with alongitudinally shiitablc weight bearing having a device for securingit"in position, substantially as herein described.

2. Alever of the second class provided with a longitudinally-shiftableweight and vertically-adjustable bearing and a device for securing it inposition, substantially as herein described.

Alever of the second class provided with a longitndinally-shiftableWeight-bearingand coupled to a vertically-adj ustable swivel-fulcrum,substantially as herein described.

4. The combination of second-class lever A, slide H, clamp-screw h,screw-threaded shank 7t, and hearing I, engaged with said shank, for thepurpose described.

5. The'combination of second-class leverA, pivot c, ears 0,screw-threaded shank D, and foot (7, engaged with said shank, for thepurpose described.

G. The combination of second-class lever A, slide II, clamp-screw 72,screw-threaded shank 7L, bearing I, pivot c, ears 0, screw-threadedshank D, and foot d, all as herein described, and for the purposestated.

In testimony whereofI aflix my signature in presence of two witnesses.

GUSTAVE II. JANTZ.
